Spartan Metals Geophysical Surveys Indicate Potential Tungsten-Silver Veins Extension at Its Tungstonia Claims, Nevada

Spartan’s geophysics confirms deep vein extensions and a porphyry target at its Eagle Project.

By The Northwire Desk — AI Analysis Sep 18, 2026 · 05:01 W · 0.48 Spartan Metals Corp.
Executive Summary

Spartan Metals Corp. has released results from magnetotelluric (MT) and direct-current induced polarization (DCIP) geophysical surveys at its Eagle Tungsten-Silver-Rubidium Project in Nevada. The surveys indicate that historical tungsten-silver veins at the Tungstonia Claims extend to depths of approximately 700 meters, maintaining their surface strike and dip. Additionally, a new 3.7 km² porphyry target was identified at depths between 400 and 1,800 meters along the NNE Sims Canyon Fault.

The company interprets the veins and porphyry target as a single, dynamic mineralizing system, identifying five priority targets for future drilling, including carbonate replacement deposits (CRD) and skarns. The ongoing 3,000-meter diamond core drilling program, which commenced in August 2026, is fully financed from existing working capital raised in early 2026. Initial drill assay results are expected to be released as they become available later in the year.

Material Impact

Geophysical data has provided structural confidence for the planned 3,000-meter drill program, though it does not constitute a resource estimate or economic catalyst. The news aligns with previous expectations set by the August 2026 drilling commencement and July 2026 vein expansion announcements. No new financial data, financing, or major corporate milestones were disclosed.

Company Overview

Spartan Metals Corp. is an exploration-stage critical minerals company focused on its 100%-owned Eagle Project in White Pine County, Nevada. The project encompasses approximately 36.5 km² and includes past-producing mines, specifically Tungstonia, Yellow Jacket, and Rees/Antelope, which generated historic tungsten production from 1915 to 1956. Primary commodities at the site include tungsten, silver, and rubidium, with secondary critical metals such as copper, antimony, and bismuth. The company is currently advancing multiple deposit types, including porphyry, skarn, and carbonate replacement deposits (CRD). Additionally, Spartan Metals acquired the Victorio Project in New Mexico in March 2026, which hosts the largest historic tungsten resource in the U.S. and is currently undergoing a preliminary economic assessment (PEA) update.
